PRODUCTION METHOD FOR NEGATIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY

摘要

The present invention relates to a production method for a negative electrode active material for a lithium secondary battery, and to a lithium secondary battery, and provides a production method for a lithium secondary battery negative electrode active material that is produced by mechanically grinding or crushing, in dry or wet conditions, particulate silicon which is in a secondary particle state formed by agglomerating crystalline and non-crystalline primary Si particles.
